Heumann Specication' of Letters Patent.

Application fued my as, 191s. semi no. 248,341.

To all whom it may concern:

Be it known that I', WiLLAno J. Noluus, a citizen of,the United States, residing at Charleston, in the county of Kanawha and Stute of West Virginia, have invented certain new and useful Improvements in eadlights, of which the following is a specifica tion.

My invention relates to improvements in lamps, adapted for use upon automobiles, railway vehicles, ships or the like.

An important object of the invention is to provide a lamp of the above 'mentioned character, having a. lens or lenses which are adjustable for directing or distributing the light over an increased area, when desired.

A further object of the invention is to vprovide means to shift the source of light,

with the angular adjustment of the lens or lenses, .so that the source of light will occupy a proper position to cause the rays of light therefrom to pass generally 4through the lenses, at a right angle thereto.

A further object of the invention is to provide a. lamp of the above mentioned character, paratively inexpensive to manufacture, and convenient in use.

Other objects and advantages of the inf' vention will vbe aparent during the course of the following escrlption.

In the accompanyin drawings forming a,

i part of this specificatlon and inwhich like numerals are employed to designate like parts throughout the same,'

Figure 1 is a plan view of a' lamp em-A bofplying my invention, l,

1g. 2 is a front end elevation of the In the drawings, wherein for .the purpose vof illustration is shown a preferred embodi ment of my invention, the numeral 10 designatos a longitudinal casing, which is preferably horizontally arranged. This longitudinalcasing is provided at its forward end -with a pair of lateral extensions 11, which which is simple in'construction, com- 'upper en are angularly arranged, and diverge forwardly. These lateral extensions have outer portions 12; which are longitudinally curved and are struck upon arcs having their oenters at 13, this numeral also designating pivot elements or pins. y

Theforward end 14 of the lon itudinal casing 10 is formed open, and is a apted to be covered by a `main lens 15, carried in a swinging frame 16. This frame is equipped' with ears or knuckles 17, which are free to turn upon the pin 13. A suitable latch 18, is

employed to retain the; frame 16 ixi the' closed position.

The numeral 19 designates auxiliary casing sections, arranged to swing within the extensions 12, and being longitudinally curved, to conform to the curvature of the same. The casing sections 19 are rigidly s'el cured to frames 20, carrying auxiliary lenses 21, as shown. The frames 20 have apertured ears or knuckles 22, receiving the pins 13, and rigidly clamped thereto. It is thus apparent that by turning the pins 13, the auxiliary lenses 21 may be swung or angularl ,ad]usted in a horizontal plane.

eens' are provided to turn the pins 13, comprisin cranks 23, rigidly secured to the s of' the pins. These cranks' extend inwardly and have overlapping slotted rod 27.

Rigidly secured to a suitable support, ini

convenient reach of the operator, 1s a tubular housing 28, receivin therein a reciprocatory rod- 29, Vhaving t e rod 27 connected therewith. Mounted upon the tubular housing 28 is a reciprocating sleeve 30. A head or button 31 is rigidly attached to the rod 29 and sleeve 30. The sleeve 30 has a lon- 32, receiving a. transversely block 33, provided with teeth teeth 35, which are formed upon the base 28. The block 33 is pivote to a thumb-lever 37. as shown at 38, and this thumb-lever is pivoted at 39. The rear end of the thumb-lever is forced upwardly gitudinal slot reciprocatory 34, to engage with by a spring 40.

The numeral 41 designates a source of light, 'which maybe an electric lamp, gas lamp, or oil lamp. This source of lightis suitably mounted upon a carriage 42, which is. movable longitudinally of the casing 10, in a manner to be described. Arranged rearwardly of the source of light 4 1 and rigidly Patented July 8,1919.`

which4 is longitudine y curved in a Ahorizonk tel plane, yes shown. 4This reflector ig `sulliciently long and is suitabl curved whereb 6 portions thereof serve to r ect li ht throug 10 horizontal arm 45, to the outer end of which eomprisi all of the lenses. The carriage is mount:-

Bigidly secured to the reflector 48'is a enerated by the -souce of li ht 41. It is?? to be taken as a preferred exemple' of the same, and that various changes in the shape.

size, and arrangement of parts muy be resorted to without departing from the spirit of the invention or the scope of the sul,- j'oined claims.

Having thus described my invention, 4l claim:

1. A lamp of the character described, u swinging lens, n source of light, an means to simultaneously swing the loris and move the source of light toward. or away from the lens.

2. lamp 0f the character described, comprising a lens adapted to he shifted in a horizontal plane to assume rlierent :ingut us seen that the lon itudinu movement of ler positions, a source/of light adopted to the 27 is utiliz to shift the carriage 42 longitudinally. I

The, operation of the lamp is as follows; When it is desired to have the rays -of li htpassing through the three lenses 15 and 2 me or form in 'eiect a si le light, the lenses l area so that t eir axes are substantial] para el with the 4exis of the .lens 15, or t e lenses 21 may have their axes Aslightly forward] converging. When the lenses 21 are in t s position, the buttonor lcnob 31 mayassume the roer position as mdicated in dotted lines in 4.

To swing the lenses 21 rearward! so that their axes diverge forwardly, the utton 31 is pushed forwardly, after the rod is released by manipulation of the thumb-lever be moved horizontally toward and uwuy from the lens, and common means to shift the lens and move the light.

3. A; lamp of the character described. comprising a relatively stationary lens, n source ofrlight arranged rearwardly of the lens and in substantial alinement with the longitudinal axis `thereof, means whereby the sour of light may be moved toward and away from the lens nt substantially :i riight angle thereto, and or. nngninl'ly a: justable lens arranged upon conside of the relatively stationary lens and adapted to be shifted to different angular positions with respect to the longitudinal axis of the relatively stationery lens.

4.. A lamp of the character described, com

37. This forward movement of the rod 29 prising a casing, a main lens connected with moves the rod 27 forwardly,l which in turn 'swi the bell'crank levers 23 forwardly, causing the casing sections 19 and frames 20 to move rearwardlv. Upon the forward movement of the ro 27, the carriage 42 'moves forwardly, thereby advancing the source .of light 41 and reflector 43, with relation to the singularly arranged 'lenses 21.

As illustrated diagrammatically in Fig. 6, the rays of light from the source of light 41,1111: retuinedmore or less perpendicular to the lenses 21, when these lenses occupy the several adjusted positions which is effected by -shifting the source of light toward or away from these lenses.

From the foregoing description it 1s obvios that rays of light pass through the mein lens 15 and are projected forwardly in a streitgg'ht` line,4while the rays of light lineassing through the auxiliary lenses 21, may

rejected forwardly in parallel relation to t e rays of light passin through the lens 15, or may assume angu arpositlons, conr verging or diver "ng with relntion thereto. YHy this Ineens t e rays of. llglilt may be spread over en area of varying sues.

It is to be understood that the form of my linvention herewith shown and described is the forward end thereof, angularly adjust able lensesconnected with the forward end of the casing and disposed upon opposite sides of the main lens, means to move the anulnrly ad'ustable lenses, n source of li t arrange within the casing rearwnrdly o the lenses, l,and mea-ns connecting the source of light and singularly adjustable lenses to move them.

5. A lamp of the character described, comprising a. casing, a main lens connected with the forward end of the casing, angulnrly adjustable 'lenses connected with the forward end of the casing and disposed upon opposite sides of the main lens, a carriage longitudinally `movubly mounted within the casing, a source of light connected with the carriage, a reflector secured to the carriage i rearwardly ofthe source of light and 'ceneting with all of the lenses,and connecting the carriage and singularly adjustable lenses to move then in umson.
